ephemeral node
Key: HBASE-9593
URL: https://issues.apache.org/jira/browse/HBASE-9593
Project: HBase
Issue Type: Bug
Components: master
Affects Versions: 0.94.11
Reporter: rajeshbabu
Assignee: rajeshbabu
In some of our tests we found that regionserer always showing online in master
UI but its actually dead.
If region server went down in the middle following steps then the region server
always showing in master online servers list.
1) register to master
2) create ephemeral znode
Since no notification from zookeeper, master is not removing the expired server.
Assignments also failing if the RS is selected as destination server.
